Jakarta–Bandung High-Speed Railway Project

Jakarta–Bandung High-Speed Railway (Indonesia)

The Jakarta–Bandung High-Speed Railway is the first high-speed rail project in Indonesia and Southeast Asia, and a flagship cooperation project under China’s Belt and Road Initiative.

The high-speed trainsets were designed and manufactured by CRRC Qingdao Sifang, based on the 350 km/h “Fuxing” EMU platform, and customized for Indonesia’s climate and operating conditions.

In this project, Conglin Aluminum supplied high-performance aluminum extrusion profiles, carbody materials, and structural modules, which were widely used in train car bodies and key load-bearing structures, ensuring lightweight design, structural strength, and long-term durability under complex operating environments.

How We Help Our Clients

Conglin Aluminum played a key role in the Jakarta–Bandung High-Speed Railway project by providing over 60% of the aluminum materials used in the train car bodies, including high-performance aluminum extrusion profiles and structural modules.

Our Contributions：

Material Supply & Performance Optimization
We supplied aluminum alloys that are specifically designed for rail transit applications, ensuring that the materials met the strength, lightweight, and corrosion resistance requirements for high-speed train construction. Our materials were used in car bodies, load-bearing structures, and safety-critical components.
Tailored Engineering Solutions
Given Indonesia’s tropical climate and unique operating conditions, our team customized the aluminum profiles to withstand high humidity and extreme temperatures. We employed advanced alloy formulations and optimized welding processes to meet the stringent requirements of the project.
Collaboration on Design and Development
In 2019, we set up a dedicated project team to work closely with CRRC Qingdao Sifang on R&D, from alloy casting and die design to extrusion and machining. Our engineers collaborated directly with the client’s design teams to ensure that every material and component was optimized for performance, durability, and manufacturability.

Result: The successful delivery of all materials, coupled with our continuous innovation and commitment to quality, enabled the Jakarta–Bandung HSR to meet the highest standards for structural integrity and performance, earning client recognition and solidifying Conglin Aluminum as a trusted supplier for high-speed rail projects worldwide.
